Originally titled 'Tribos-Mini Toolholder Clamps 0.3-mm Tools'
The Tribos-Mini from Shunk directly clamps the smallest of tool shanks consistently along the entire axis. Machining medical, dental and micro level parts are the most challenging applications faced today. This toolholder is designed to eliminate troublesome collets, collet nuts and inconsistent tool clamping.
With a run-out accuracy of less than 3 microns and a balance grade of G2.5 at 25,000 rpm, high rpms and fast feed rates are achievable, according to the company. The design allows direct clamping through the elasticity of the toolholder material. The Tribos technology utilizes a polygon form in the clamping bore to generate the clamping.
Cutting tool clamping results are simplified without the influence of an operator. The holder is inserted into the press and the cutting tool is released in less than 30 seconds.
The SVP-Mini clamping device enables Schunk Minis to be clamped simply for micromachining as far as the back stop, saving time and significantly reducing setup costs, the company says.
The SVP-Mini can be fastened both horizontally and vertically to the workbench while direct clamping and unclamping on the spindle are also possible.
